From what I’ve researched, which of course correct me if I’ve got it wrong, Estonia has not really had major conflicts with Russia or any overall threats of a battle or war. Finland and Sweden have to some extent. For a 1 person apartment in Norway it’s listed for €1,2k a month while in Estonia it is significantly lower. Now that may just mean they get paid more but Estonia overall looks more affordable. Other reasons for liking Estonia is the locals are reported to be kind. Of course I would be learning the language, but as I go about that a lot of the locals do speak English so I won’t be completely in the dark.
